To all 996 owners with PSE, especially those with a 4S.
I think my 996 C4S exhaust behaves oddly. I think it's a fault but you might tell me it's normal behaviour. The problem is that I've always had this 'fault' on my car so I don't know if it's a fault or intentional behaviour. If you have the same car, perhaps you can shed some light on this.
When I start it, it's noisy and sounds great. It quiets down as it runs for the first 5 mins.
I have the PSE system and when I press the button you can audibly hear the exhaust note change - quieter when on and louder when off. Default is off so loud.
Here's the rub. Up to around 1500rpm it's got a good noise then it fades out to the point where it's so quiet it's like driving my partners Yaris. If I keep accelerating, when I get to around 3500rpm the exhaust suddenly gets loud again. I mean it's immediate - like someones flipping a switched marked loud. It sounds great.
It happens in 2nd and 3rd gears most noticeably and the PSE is in the 'off' position. If I have the PSE button on, then it's just quiet all the time and that works fine.
So why the silent spot?
I did read somewhere that German market cars might have had a system that turns on and off the PSE at certain speeds to prevent people driving round residential streets with a loud exhaust but information is thin and I don't think I was ever on UK cars.
I have also had a small go at checking vacuum pressure at idle on both sides of the Y piece in the engine bay but both hold good pressure. One side has only a microscopic leak but not enough to cause this kind of issue.
1999 986 2.5 Boxster. (5 spd)
Not many problems with the car but cruise control doesn’t work and the spoiler only extends halfway or so.
Current actual problem with the car is that I can feel vibration or shaking in the steering wheel (and in the car to a much lesser extent) after shifting into fourth gear. After shifting into fourth gear, the shaking seems to persist even as I slow down, or after shifting into fifth. It will persist even if I shift into neutral but will stop after I come to a stop.
It’s strange to me that this is the case when gears 1-3 don’t have this problem. I am guessing that it’s an issue with bearings or alignment in the front wheels since i’m feeling the vibrations in the wheel but hopefully someone here has a better idea.
Tried googeleing it but couldn’t find what I was after. Was curious if anyone knows what type of flat 6 the 986 boxster has?
Is it a a true boxer engine? Or a horizontally opposed flat V? True boxer meaning it has individual crank pins for each piston and is a true 180degree angle. Thanks in advance
I'm new to the Porsche family.... Just over a month and the proud owner of a 1999 Boxster. It's a project car but still on the road and my point to point ride. Must say, LOVE to drive this car....This one has been lowered some, well alot... and does it hug the road..... Just doesn't miss much being that low.... My question is, I am having an issue with the rear lights on this car... I know I had a problem with the left rear brake light. I tried tracing back the wire but found no problem... I then switched the lamp holder from the right side to the left and all the lights worked... So I thought I had an equipment issue. I bought a (Porsche) replacement bulb holder. Came in last night. Changed out today...Guess what???? Turn indicators work, Backup lights work, Brake light works on the Right Side ONLY, (still) Now no rear tail lights what so ever......I have checked ALL the fuses, only had to replace one and it had nothing to do with the lights. NOTHING has changed....Where did my tail lights go?????? Can't figure this out.......Please help.......Just FYI, ALL the LIGHTS were working as of last Wed. when I did the bulb holder swap and checking the lights. Power is to both wire harnesses. Everything else works except the left brake light and the drive lights. Go figure.......
